Low-dimensional electronics

The symmetries of an atomic crystal govern its electronic properties through the formation of energy bands, bandgaps and selection rules; yet this picture breaks down when electron-electron interactions grow strong enough to give rise to entirely new many-body phases. In one and two dimensions, the strength of these interactions is enhanced, making low-dimensional systems prime candidates for understanding the origin of emerging electronic phases, with direct relevance for metrology and quantum computing. Our group addresses this challenge experimentally by combining nanofabrication of graphene structures, nanophotonic probes and quantum transport at ultra-low temperatures to induce, control and explore strong electron interactions in one- and two-dimensional systems.
